HolsTlNG AND ooN SPECIFICATION forming part of Letters Application filedApril 4, 1892.

T0 all whom, t may concern.:

Beit known that I, GEORGE I-I. HULETT, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful l-Ioisting and Conveying Apparat-us,ot' which the following is a description.

My invention relates to improvements in a hoist and conveyer combined,in which the rear portion of a track is rigidly attached to thesupporting-frame and the forward portion back of the boom rests upon theframe by means of a suitable support, which permits the forward part ofsaid track, together with the boom and mast, to be drawn to one side orthe other as far as the iiexibility ot' the material of which the trackis composed will permit.

In a machine design ed to hoist and convey material from a boat to ashed or trestle and having a track suspended from the frame of the sameit is necessary to provide some way to move the boom radially on ahorizontal plane to adjust it to the different hatches where two or moreconveyers are unloading one and the same boat. The distance from thecenter of one hatch to the center of another ranges from twelve feet tothirty feet in some boats and on different boats, so that if the boomsare fixed at a given point they are not often in the right place overthe centers of the hatches where two or more are used, and it is the object of my invention to overcome this difficulty. l attain this object bythe means illustrated in the accompanying drawings and described in thefollowing specification, in which Figure 1 is a side view of my device;Fig. 2, an enlarged end viewof the same, and Fig. 3 a top view.

Similar letters refer to similar parts thro ughout the drawings andspecification.

The boom A, Figs. l and 3, is hinged at B to the track C, so that it maybe raised to a perpendicular position when not in use. The wagon E,Figs. l and 3, with the load F sus pended therefrom, is caused totravel,drawn by the rope D, running to any suitable windingdrum alongthe boom A and track C. To the forward portion of the track C are fixedthe supports G G,which are designed to move on the frame I-l l-l throughthe medium of the PATENT OFFICE.

rollers l, Figs. l and 2, said rollers constituting a part of thesupports GG. To the frame J, Figs. l and 3, and to all supports back ofsame, the track C is rigidly connected, and since the track C issecurely attached to the supports G G it will be readily seen that anymovement of the supports will also move that portion of the track Cforward of the frame J.

The mast K, attached to the center of the support G, has the guy-line L,Figs. l and 2, by means of which the boom A is raised or lowered andwhen lowered supported at its front end by said guy-line. The guy-linesM M', Figs. l and 3, are attached to opposite ends of the support G andthe sides of the boom A, for the purpose of preventing any swaying orlateral motion of the boom A.

In operation the boom A is lowered over the boat and the track Csuspended from the supports G G', the whole supported by the rollers l,and is drawn along the frame l-I H until the boom A is verticallyoverthe hatch ot' the boat to be unloaded, as illustrated by the dottedlines in Fig. 3. The load F is then raised and drawn along the boom A onthe track C by means of the rope D. Since the track is rigidly attachedto the framework J and to all supports back of same, itwill readily beseen that when said track is moved radially at the point or support G itwill take the form of an arc of a circle, around which the wagon E willtravel to the rear of the shed, where the track C is yielding enough toThe mast K, being attached to the support G, will necessarily travelwith the same and therefore the guy-line L must always be taut. Thesupport G, to which the guy-lines M M from the sides of the boom A areattached, being at right angle to the track C, and since the boom moveswith the track, the guy-lines M M must remain taut, thereby steadyingthe boom and keeping it always at right angle to the support G.

The guy-lines m fm radiating from a common center on the frame J to beattached to opposite sides of the support G, must always be taut andsupplement the guy-lines M M', supporting the boom A.

What l do claim as my invention, and desire to secure by Letters Patent,is
